Each business on Facebook has a section to keep track of Mentions on Facebook, e.g.

https://business.facebook.com/yourbusiness/notifications/?section=activity_feed&subsection=mention

In Facebook Integration settings, there is no option to include those Mentions and let them create Tickets like other Facebook activity

https://yourdomain.zendesk.com/agent/admin/facebook

The only thing I can find is discussion from 6 years ago: https://support.zendesk.com/hc/en-us/community/posts/204248887-Facebook-mention-integration

which probably didn't lead to any solution.

It is essential for us to be able to track ALL activity from Social media and getting that into our Customer Service tool. Going back to using several tools to keep overview is not what we expected when joining Zendesk.
